tsis muaj. GRE yog cov txheej txheem siv nrog PPTP, tab sis nws tuaj yeem siv los ua ib qho kev sib koom ua ke tunneling ib yam nkaus. Koj tuaj yeem (thiab yuav tsum) encrypt/tunnel a L2 TP kev sib txuas hauv IPSec qhov, vim qhov ntawd yuav muaj kev nyab xeeb dua ua.

Ua raws li qhov xav tau, l2tp siv dab tsi los encrypt cov ntaub ntawv?

L2 TP stands rau Txheej 2 Tunneling raws tu qauv, thiab nws tsis muab ib yam encryption los ntawm nws tus kheej. L2 TP feem ntau siv ib qho kev lees paub raws tu qauv, IPSec (Internet Protocol Security). Nws siv nws rau zog encryption thiab authentication. IPSec muab nws qhov kawg ntug ntawm qee qhov feem ntau siv raws tu qauv zoo li PPTP.

Ib yam li ntawd, GRE qhov yog dab tsi? Generic Routing Encapsulation ( GRE ) yog cov txheej txheem uas encapsulates pob ntawv txhawm rau xa lwm cov txheej txheem hla IP network. GRE yog txhais los ntawm RFC 2784. GRE tau tsim los ua ib tunneling cov cuab yeej txhais tau tias nqa ib qho OSI Layer 3 raws tu qauv dhau ntawm IP network. GRE tunnels muab kev daws teeb meem rau kev sib koom tes nrog kev txwv hops.

Kuj paub, vim li cas l2tp VPN raws tu qauv zoo dua PPTP?

Cov L2TP raws tu qauv muaj kev ruaj ntseg dua tshaj PPTP vim nws tsis muaj tej yam kev ruaj ntseg vulnerabilities loj thiab siv cov IPSec suite muab qhov kawg-rau-kawg encryption, cov ntaub ntawv keeb kwm authentication, kev tiv thaiv replay, nrog rau cov ntaub ntawv ncaj ncees.

Qhov twg ntawm cov txheej txheem hauv qab no Pptp siv rau kev lees paub?

PPTP yog raws li Point-to-Point raws tu qauv (PPP), uas yog feem ntau siv rau dial-up kev sib txuas. Thaum ib qib siab dua kev lees paub txoj kev yog siv , PPTP txhawb Microsoft Point-to-Point Encryption (MPPE), ib txoj hauv kev muaj zog ntawm encrypting VPN kev khiav tsheb ua ntej tso cai rau nws hla mus rau pej xeem network.
